class RemiAudio::DSP::BiquadLP
- RemiAudio::DSP::BiquadLP
- Reference
- Object
Overview
A digital biquad lowpass filter.
This is identical to using a normal BiQuadFilter instance, except it is
optimized strictly for lowpass usage and includes the LPFilter module.
Included Modules
Defined in:
remiaudio/dsp/biquadlp.crConstructors
-
.new(newSampleRate)
Creates a new
BiQuadFilter.
